[0039] Embodiment 1

[0040] See also Figures 1 to 5 As shown, the water vapor separation device provided in the present application is used for the air inlet of the automobile air conditioner. When the external air flows through the water vapor separation device, the water vapor separation device can separate the moisture in the air to reduce the humidity of the air entering the automobile air conditioner.

[0041] Specifically, the water vapor separation device includes a water storage box 101, an air intake pipe 102 and a drying element 103; the water storage box 101 is provided with a water storage chamber, a first inlet 106 and a first outlet 107, and the first inlet 106 and the first outlet 107 are connected to the water storage chamber; the air intake pipe 102 is provided with a rotating channel, a second inlet 108 and a second outlet 109, and a rotating channel is formed between the second inlet 108 and the second outlet 109; the first outlet 107 is connected to the second inlet 108, and the second outlet 109 is connected to the air inlet of the automobile air conditioner, and the drying element 103 is located between the second outlet 109 and the air inlet of the automobile air conditioner.

[0042] Specifically, when the automobile air conditioner is turned on, external air can be sucked into the water storage box 101 from the first inlet 106. Under the action of gravity, rainwater can fall to the bottom of the water storage box 101, and the rainwater is collected in the water storage cavity, so that most of the rainwater can be separated. Then the air enters the air intake duct 102 through the first outlet 107 and the second inlet 108. The air intake duct 102 is provided with a revolving channel. When the air enters the revolving channel, the air flow direction forms a "U"-shaped flow path, which can decelerate the air in the air intake duct 102. The micro-particles of rainwater in the air can be condensed and collected at the bottom of the revolving channel, so that the trace moisture inhaled or splashed into the air intake duct 102 can be deposited in the air intake duct 102 to achieve further separation of rainwater.

[0043] A drying element 103 is also provided at the second outlet 109 of the rotary channel. The air flows through the drying element 103 and enters the air inlet of the automobile air conditioner. The drying element 103 is mainly responsible for drying and dehumidifying the air with high humidity, and can effectively block dust particles. As the last line of defense for air entering the automobile air conditioner, the drying element 103 not only dries the air and blocks dust, but also has a certain silver ion disinfection and sterilization effect.

[0044] The drying element 103 specifically includes a non-woven fabric and a drying box, and air can flow through the non-woven fabric and the drying box in sequence. The non-woven fabric is installed at the second outlet 109 through a fixed pressing plate. The drying box is installed at the second outlet 109 and a sealing sponge is arranged around the drying box. The main components of the drying box are granular activated carbon, anhydrous calcium chloride, silica gel and other materials.

[0045] The water vapor separation device provided in the present application can separate rainwater and air multiple times by providing a water storage box 101 and an air intake pipe 102, and further dehydrate the air at the end of the air intake pipe 102, thereby making the air entering the car air conditioner drier, improving the air quality in the car, achieving the purpose of mildew prevention, and enabling the car air conditioner to heat and cool quickly.

[0046] In the optional solution of this embodiment, Figure 4 As shown, the air intake duct 102 includes a rotating portion 110 and a connecting portion 111. The second inlet 108 is opened in the rotating portion 110 so that the rotating portion 110 is connected with the water storage box 101, and the air in the water storage box 101 can directly enter the rotating portion 110. The rotating portion 110 is similar to a snail shell structure and is in a winding spiral shape, thereby forming a "U"-shaped flow path, so that the air entering the rotating portion 110 is decelerated, and the micro-particles of rainwater in the air can be condensed and collected at the bottom of the rotating portion 110.

[0047] The connecting portion 111 is connected to the rotating portion 110, and the second outlet 109 is provided in the connecting portion 111; the connecting portion 111 forms a connecting passage extending in a straight line direction, and the second outlet 109 is located at the end of the connecting passage. Specifically, the connecting portion 111 extends upward in an inclined straight line direction, the bottom end of the connecting portion 111 is connected to the rotating portion 110, and the top end of the connecting portion 111 is provided with the second outlet 109, and the actual position of the second outlet 109 is adapted to the air inlet of the automobile air conditioner. In this way, the bottom of the rotating portion 110 can be the lowest point of the air intake duct 102, so that the micro-particles of rainwater can condense at the bottom of the air intake duct 102, and prevent the flowing air from driving the rainwater into the automobile air conditioner.

[0048] In an optional solution of this embodiment, the rotating part 110 and the connecting part 111 are surrounded to form a receiving space 112, and the water storage box 101 is embedded in the receiving space 112, which can make the overall assembly structure of the air intake pipe 102 and the water storage box 101 more compact and reduce the space occupied.

[0049] In the optional solution of this embodiment, Figure 5 As shown, the water storage box 101 includes a first top wall 104 and a second top wall 105. The first top wall 104 is adapted to the contour of the automobile hood, so that the overall appearance is consistent. The first top wall 104 is provided with a first inlet 106 so that air can enter the water storage box 101 from above, and rainwater is deposited below the water storage box 101. The second top wall 105 is inclined relative to the first top wall 104, and the second top wall 105 is provided with a first outlet 107, and the first outlet 107 is located obliquely above the water storage box 101. In this way, the height of the first outlet 107 can be made to have a certain distance from the bottom of the water storage box 101, and the flowing air is not easy to bring rainwater into the air intake pipe 102. The first outlet 107 is inclined, and the second inlet 108 that is connected to it and opened in the air intake pipe 102 is also inclined, so that the bent rotating part 110 will not be too protruding and interfere with the hood.

[0050] In an optional solution of this embodiment, the water storage box 101 also includes a guide wall 113; the guide wall 113 is inclined and opposite to the first inlet 106 to guide the water flow to the bottom of the water storage box 101; a water absorbent pad 114 is arranged on the guide wall 113.

[0051] In this embodiment, the inclined guide wall 113 can be matched with the connecting portion 111 of the air intake duct 102. When rainwater enters the water storage box 101 from the first inlet 106, the rainwater can flow along the inclined guide wall 113 to the bottom of the water storage box 101. A water-absorbing pad 114 is also provided on the guide wall 113. The water-absorbing pad 114 is specifically a sponge. The sponge has a certain water absorption and buffering effect, which can effectively prevent the splashing of rainwater entering the box and play a role in buffering rainwater.

[0052] In an optional solution of this embodiment, a first discharge port is further provided at the bottom of the water storage box 101. When rainwater enters the water storage box 101 from the first inlet 106, the rainwater can be collected in the water storage cavity, and the collected rainwater can be discharged to the outside of the vehicle from the first discharge port. The height of the first inlet 106 and the height of the first outlet 107 are both higher than the first discharge port, which can prevent rainwater from entering the air intake duct 102.

[0053] Furthermore, a second discharge port is provided at the bottom of the air intake duct 102, and the micro-particles of rainwater condense at the bottom of the air intake duct 102, so that the rainwater can be discharged to the outside of the vehicle from the second discharge port. The height of the second inlet 108 and the height of the second outlet 109 are both higher than the second discharge port, which can prevent rainwater from entering the vehicle air conditioner.

[0054] In an optional solution of this embodiment, the water storage box 101 further includes a first bottom wall 115, a first confluence groove 116 is provided at the lower end of the first bottom wall 115, and a first discharge port is provided at the bottom of the first confluence groove 116 to prevent water accumulation in the water storage box 101. The air intake pipe 102 includes an inclined second bottom wall 117, a second confluence groove 118 is provided at the lower end of the second bottom wall 117, and a second discharge port is provided at the bottom of the second confluence groove 118 to prevent water accumulation in the air intake pipe 102.

[0055] In an optional solution of this embodiment, a first drain pipe 119 is provided at the first discharge port, and a second drain pipe 120 is provided at the second discharge port. The second drain pipe 120 is connected to the first drain pipe 119 to form a siphon effect.

[0056] In this embodiment, the first drain pipe 119 is used to drain the rainwater in the water storage box 101, and the second drain pipe 120 is used to drain the rainwater in the air intake pipe 102. The first drain pipe 119 and the second drain pipe 120 can be made of high and low temperature resistant rubber material, and the first drain pipe 119 is connected to the first drain port through a clamp, and the second drain pipe 120 is connected to the second drain port through a clamp. The first drain pipe 119 and the second drain pipe 120 are fixed inside the car cabin with a clamp.

[0057] In addition, since the amount of rainwater in the water storage box 101 is larger, the diameter of the first drain pipe 119 is larger than that of the second drain pipe 120 to achieve a quick drainage function. Furthermore, the end of the second drain pipe 120 away from the air intake pipe 102 is connected to the middle position of the first drain pipe 119. When the first drain pipe 119 drains water, the second drain pipe 120 can form a siphon effect, so that the water inside the air intake pipe 102 can be drained cleanly.

[0060] In an optional solution of this embodiment, the water-gas separation device further includes a first filter element and a second filter element 121. The first filter element is specifically a grille and is located at the first inlet 106, and is used to prevent visible objects of larger volume or area, such as leaves, branches, and insects, from entering the water storage box 101. The second filter element 121 is specifically a filter mesh made of metal (12 meshes can be selected), and the filter mesh is located between the first outlet 107 and the second inlet 108, and can filter missed debris and smaller debris for a second time, and can prevent rainwater from being sucked into the air intake pipe 102 to a certain extent. In practical applications, filters of different specifications can be selected according to filtering requirements.
